Bond Types
Step 1: use the electronegativity chart to determine the type of bond formed
between each of the following element pairs
Step 2: Determine which of the elements in the pair is more electronegative and
do the following:
If it is an ionic bond mark the more electronegative element with a
-
negative sign (
) & mark the less electronegative element with a
+
positive sign (
).
If it is a polar covalent bond mark the more electronegative element
-
δ
with a partial negative sign (
) & mark the less electronegative
+
δ
Or
element with a partial positive sign (
).
use a dipole arrow (
)
to indicate the electronegativities.
If it is a nonpolar covalent bond, IT’S NEUTRAL, so don’t do anything!
